SMOKING PIPE Tokusaburo Mochizuki, San Francisco, Calif. Application December 14, 1939, Serial No. 309,175

3 Claims.

This invention relates generally to improvements in smoking pip'e'sand has particular reference to improvements in the-bowl section of the pipe whereby at least two tobacco containing chambers may be formed in the bowl of said pipe.

Another object of the invention is to provide a smoking pipe of the character set forth wherein the smoke from the bowl to the smokers mouth travels through a tortuous path, thereby cooling the smoke.

A further object of the invention is to provide a smoking pipe of this character which includes at least two tobacco containing chambers and means for alternately closing and opening these chambers, whereby the pipe may be filled and smoked from either chamber of the bowl.

A further object of the invention is to provide a smoking pipe of this character that includes more than one tobacco containing chamber, one or both of which may be normally closed by a plate rotatably mounted upon the top of the bowl of the pipe, which chambers may be alternately covered or uncovered through the medium of an opening in the plate, whereby either chamber of the bowl may be alternately opened.

A further object of the invention is to provide a pipe of this character having a bowl provided with a removable threaded chamber at its lower end, whereby the pipe may be thoroughlycleaned when desired.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a side elevation of a pipe including my improved bowl and other elements constituting the invention;

Fig. 2 is a top plan View of the same, showing the bowl and its segregated chambers and portions of the plate being broken away;

Fig. 3 is a vertical section taken through the pipe bowl and indicating the ducts leading to the stem of the pipe, as indicated by the line 3-3 in Fig. 2.

Fig. 4 is a transverse section of the bowl of the pipe, further illustrating the configuration thereof and the ducts formed therein; and

Fig. 5 is a top plan view per se of the pipe bowl and ducts formed therein, showing the particular arrangement of the tobacco chambers in the pipe bowl and the ducts connecting each of so the chambers.

The invention resides primarily in a smoking pipe having the usual bowl 6 and stem 1. The bowl 6 is preferably provided with at least two tobacco containing chambers 1' and 8, and the lower end of the bowl of the pipe is provided with a screw threaded cap member 9 which encloses the lower end of the bowl.

The upper end of the bowl is covered by a plate 9 rotatably held in position by a screw 10, which screw l0 extends into a central part II formed in the bowl of the pipe. An additional rotatable plate I2 is mounted upon the plate 9 and is movable thereon for the purpose hereinafter specified.

Referring now to Fig. 2, it will be noted that ducts l3 and I4 extend through the bottom section of the bowl of the pipe and emerge in the chamber formed in the cap member 9. These ducts connect, respectively, the chambers I and 8 of the bowl. A duct l5 extends vertically through the bowl of the pipe and communicates with the chamber l6 and extends horizontally under the plate 9, thence downwardly and to the stem of the pipe, as indicated by the numeral l1. It will be observed that the rotatable plate 9' is provided with an opening I9 which may correspond with either the chamber 1 or the chamber 8, whereby the pipe may be filled with tobacco and smoked through either of the chambers, depending upon which way the plate is rotated.

The plate I2 is merely iorthe purpose of swinging about and covering the opening IS in the plate9' when the pipe is carried in the pocket of the smoker.

It will thus be noted that when nicotine collects in any section of the pipe or in the ducts thereof, the cap member 9 may be removed, which cap member 9 is threaded on the bowl as indicated at l8, and the plates 9 and I2 may also be removed by the removal of the screw I0. Therefore, all ducts may be opened for cleansing of the bowl by the introduction therein of any well-known pipe cleaning instrument.

Therefore it will be observed that a pipe of this character having a bowl employing two toa tobacco chamber is emptied to produce a proper draft through the stem from a filled chamber of the pipe.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims. I

Having thus described my invention, I claim:

1. In a smoking pipe of the class described including a bowl having chambers formed therein, a cap member closing the bottom thereof, a stem integrally formed with said bowl, ducts extending through said bowl and communicating cap arranged on the lower end thereof and forming a chamber, a plate arranged upon the upper end of said bowl, a swingable element capable of alternately closing either of said chambers, ducts communicating with the interior of said cap and communicating with said chambers, and additional ducts arranged in said bowl and communieating with the interior of said cap, whereby smoke may be drawn from either of said chambers through the stem of the pipe.

3. In a smoking pipe of the class described including a bowl and an integrally formed stem, said bowl having at least two tobacco containing chambers formed therein and having a cap member closing the lower end thereof, ducts extending through the bottom of each of said chambers and communicating with a duct formed in the stem of the pipe, and means for closing the upper end of the bowl of the pipe, said means consisting of a swingable plate adapted to selectively control the draft from one or the other of the chambers of the pipe.
